Does Cisco sf200-24 and sf200-48 have snmp config in Gui?? 

I have me3400 when I connect an pc cable or a phone cable it's not connect to the network i delete everything in the switch and the same problem still there 

i have a cisco switch series 3400 . i configured a voip in it and the ip phone on same switch can call each other but i don't hear anything at the same time calling another phone on other switch it works normally
